Abstract
The mathematical modeling of operating regimes of parametric THz devices based on graphene metamaterials (graphene‒dielectric periodic structures (GDPSs)) has been carried out by solving a nonlinear 3D diffraction problem for Maxwell’s equations in the projection integral form. Using an algorithm for computing bifurcation points of the nonlinear Maxwell operator, the threshold pump wave amplitudes have been calculated at which an unstable mode of the parametric excitation of electromagnetic waves occurs in GDPS-based THz device.
基于石墨烯超材料的太赫兹器件中波的参量相互作用
摘要 通过以投影积分形式求解麦克斯韦方程的非线性三维衍射问题，对基于石墨烯超材料（石墨烯-介电周期结构（GDPS））的参数太赫兹器件的工作状态进行了数学建模。利用计算非线性麦克斯韦算子分岔点的算法，计算出了阈值泵浦波振幅，在该振幅下，基于 GDPS 的太赫兹设备会出现电磁波参数激励的不稳定模式。
